IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 193,983,

June 28,1877.

To all whom it may concern Be it known that I, JOHN F. MEAD, of De Kalb,in the county of De Kalb and State of Illinois, have invented certainnew and useful Improvements in Plows; and I do hereby declare that thefollowing is a full, clear, and ex act description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thelet ters of reference marked thereon, which form a part of thisspecification, and in which- Figure 1 is a side elevation of my improvedplow, and Fig. 2 is a plan view of the same.

Corresponding parts in the two figures are denoted by like letters.

This invention relates to a certain improvementin plows, particularly ofthat class termed sulky-plows; and it consists of mechanism forinserting the plow into the ground at the running depth, substantiallyas hereinafter more fully set forth.

In the annexed drawing, A refers to an axle, upon one end of which is awheel, B, and

pivoted to the other end is a lever, I), having an arm, b, provided witha short axis having a wheel, B. A toothed segment, 0, is also attachedto the lever end of the axle A to receive a. detent, a, upon the leverb, in order to retain the said lever in position. The upper or rod a ispivoted or hinged to a lever, a, pivoted to the hand-lever b, andpressed upon by a spring, 0?, to retain the said detent in between theteeth of the segment 0.

By pressing upon the lever a the said detent will be retracted ordisengaged from the toothed segment 0, in order to vary the rela tiveposition of the axle and the wheel B upon the land-side as the wheel Bsinks into the furrow, and thus cause the axle to maintain a horizontalposition. I

Upon the axle A is mounted the drivers dated August 7, 1877 applicationfiled seat D. E is the plow-beam, pivoted, a short distance from itsrear end, to forward-projectin g arms 0 c of axle A, and preferablyslotted at said end to receive and permit of the attachment thereto of alink or plate, 0, piv- 'oted or connected to a lever, F, hinged orpivoted to the axle A.

By this arrangement it will .be seen that, by moving or pressing thelever F backward, the heel of the plow, attached in the usual manner tothe beam E, will be elevated, so as to cause its point to be inclinedand inserted into the ground upon commencing to plow.

G is the tongue, pivoted to a standard, 01, secured upon the beam E.crumed to the beam E, and extending up alongside the tongue G betweentwo stops, 6 f, upon the said tongue. A rope or chain, I, or itsequivalent, is attached to the forward end of the beam E, and passes upover a pulley, J, in the tongue, and is attached to the lever H.

It willbe observed that by moving the lever H rearwardly the forward endof the beam E will be elevated, which, in turn, will lift the plow-pointout of the ground, and thus stop the operation of plowing.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination of the axle A, having the forward-projecting arms 0 c,the plow-beam E, pivoted to axle-arms c c, and the elbowlever F, hingedto the axle and linked to the rear end of the plowvbeam, substantiallyas shown and described.

In testimony that I claim the foregoing as my own I hereunto affix mysignature in presence of two witnesses.
